apollo_readBeta: Reads parameters from file

Description

Reads in parameters from a previously estimated model and copies the values to the given apollo_beta vector, only for those parameters whose name matches.

Usage

apollo_readBeta(
  apollo_beta,
  apollo_fixed,
  inputModelName,
  overwriteFixed = FALSE
)

Arguments

apollo_beta

Named numeric vector. Names and values for parameters.

apollo_fixed

Character vector. Names (as defined in apollo_beta) of parameters whose value should not change during estimation.

inputModelName

Examples

# NOT RUN {
### Define starting values and fixed parameters
apollo_beta <- c(asc1=0, asc2=0, b1=0, b2=0)
apollo_fixed <- c("asc1")
# }
# NOT RUN {
## Not run:
### Update starting values
apollo_beta <- apollo_readBeta(apollo_beta, apollo_fixed, 
                               "oldModelName", overwriteFixed=FALSE)
## End(Not run)
